Factors Influencing Detection Time

  • Frequency of Use: Regular cannabis users may have THC detected in their saliva for a longer period compared to infrequent users.
  • Method of Consumption: THC is detected faster and for a shorter duration when inhaled or vaped compared to ingested forms like edibles.
  • Body Metabolism: The speed at which the body metabolizes THC can influence detection times. Individual variations in metabolism can lead to THC staying in saliva for longer or shorter durations.
